Hi all,

I'm moving a cluster to a new network, but I'm having more trouble that 
it should probably be.

I think I'll just build the cluster again from scratch. In any case, I'd 
like to find out what is going on with the nova db tables users and 
projects. They are empty, yet I can see defined users and projects in 
horizon. What gives?

The real error is:

Yes, I deleted that a while back. I don't know why it's still referring 
to it. The reason why I started investigating projects is because from 
looking at nova/db/sqlalchemy/api.py it looks like the project is 
associated with a network and this is where it gets the network ID. It's 
seems there is something missing or in transition. What ever it is, it's 
not functional.
